We were processing transactions, but they were not appearing in logs due to a database issue; as @edp noted above, this is now resolved;

Our system was generating thank-you/notification emails, but Amazon was refusing to actually send them, as we'd reached our sending quota for the day due to the above issue that was spewing out error emails to our sysadmin; we're working to clear this up with Amazon, at which point any backlogged emails should start churning out automatically.

So the good news is, none of our clients will need to do anything about the affected transactions; they should all show up in logs now, and emails should all go out in due course.

We apologize to everyone for the inconvenience and concern, with thanks for your patience and understanding.

Why would it process transactions I have already refunded? I refunded all the transactions today due to the delay and people opening cases against me and now they get free product. In addition to the lost sales since I had to shut everything down.

Our system already processed the transactions before you refunded them; they just weren't showing up in your Transaction Log, and the emails were backlogged in our outbound mail queue waiting to get sent. However, as soon as you refunded them in PayPal, that should have instantly expired any links we'd issued for those orders.

Hi, sorry to hear that. We haven't had any other reports of delayed orders, you can check the status of any transactions within your PayPal account in your IPN history to see if something is pending or if it failed to send... you can also resend a notification if necessary.

If you happen to find that your IPN settings at PayPal are completely disabled you will need to enter a Notification URL to turn them back on. You can use this URL to fill that field if you don't have one of your own:https://www.e-junkie.com/ecom/ipn_ext.php

AlexanderG - Thanks for letting us know that the IPN is showing to be queued at PayPal. Other transactions I've been checking on today have taken an hour or more to be reported to us. If the IPNs for these missing transactions are showing to be "Queued" rather than "Sent" then we're stuck waiting for PayPal to actually send them over.
